  7. Abstract:
  8. In this research, the trends of trade and transportation for the 10 subdivisions of food products and food products as a whole product based upon Standard International Trade Classification, SITC, have been appraised during the time period covering 1965 to 2005 among 125 countries in Asia, Europe and Africa. In this respect, the data of trade for the mentioned goods was gathered and other variables including gross domestic product, population, access to the international waters and area of countries and three transportation networks comprising two multimodal transportation networks and a unimodal network, during the cited period and for 125 countries was gathered. Then, regressions of trade versus time for export and import of products were drawn and exhibited that the trade of all products is increasing. This increase was in particular noticeable after 1990. Thereafter, gravity models of trade by all of the mentioned variables were developed. These models indicated that the effect of gross domestic product and transportation variables on trade is more significant than that of other variables on trade. Thus, gravity models of trade by gross domestic product and each transportation variable were developed for 9 cross sections and for each product. Afterwards, according to the elasticity of trade with respect to transportation in gravity models calibrated, the trends of trade and transportation for each product and each network during the time period were acquired and these trends were compared to each other. These trends were ascending for most of products signifying that the impressibility of trade from transportation variables was increasing during the time period. Furthermore, via linear programming, it was determined for each product how optimum the flow of trade distribution, regardless of the costs of production of the cited commodities, was in relation to the transportation networks and how this flow was changing during the mentioned time period. The result of this section indicated that for all subdivisions of food and live animals and food and live animals as a whole, the discrepancy between the observed trade distribution and optimum trade distribution was increasing. Moreover, after 1990 when the trade of mentioned products was conspicuously increasing, this discrepancy was intensified
